Road conditions

A recent article on NPR stated that it would take $2 billion over the next decade to repair roads in Maine and "[t]he congressionally appointed National Surface Transportation Policy and Revenue Study Commission estimates that the cost of needed repairs is $220 billion -- at a minimum -- per year" to repair all of the nation's roads. This is seen as a crisis that requires federal subsidization and massive increases in federal and state funding. They are therefore starting to look at increasing gasoline taxes.

The last substantial increase in federal gasoline taxes took place in 1993. Given that we "only" used about 142 billion gallons of gasoline in 2006 (and similarly for 2007; high prices have caused a stagnation of fuel consumption), that means the federal government "only" collected about $26 billion. Given that the aggregate state collection is similar (state fuel taxes vary considerably, but average right around $0.18 as I recall), then "only" about $50 billion or so of the $220 billion is being collected. Your fuel taxes therefore need to climb from a combination of around $0.36 per gallon to something more in the neighborhood of $1.62, an increase of $1.26 per gallon.

May I suggest something else? What about supporting tolls? Though perhaps not very practical for intracity driving, they are eminently practical for freeway and bridge traffic. But first, there is a substantial obstacle to overcome: the belief, widely held in the US, that driving cars is a right and that roads should always be free. Clearly, we understand that roads and bridges are not really free, but the costs are hidden rather than explicit [1]. Tolls are a way of making those costs explicit.

As an exercise in noting how bad the anti-toll and especially anti-private infrastructure bias is, I will cite the Forbes article cited recently in the comments at MR as an example. The Ambassador Bridge is a privately built, privately owned bridge from Canada to the US near Detroit. It is the most popular bridge in the Great Lakes region: 3.3 million cross on the Ambassador vs. 3.6 million on the other four bridges combined. On 9/11, local government officials closed off the nearby car tunnel, and traffic subsequently backed up on the Ambassador. Truck wait times went to 12 hours because of the lack of border Patrol and Customs inspectors.

The tone of the article is as follows: Because some private person had the foresight to build a bridge at that location 75 years ago, and because it is the most popular truck crossing today, and because the state has not built a competing bridge nearby, somehow the owner is a bad guy. And because 9/11 brought about panic and security precautions that caused backups, the owner is a bad guy. And most of all, because he doubled toll rates for trucks and quadrupled them for cars in the past 25 years, he is a bad guy. Bottom line: private infrastructure is bad [2].

The point about toll raises is misleading. If there are four hour weight times at rush hour, this is a sure signal that the tolls are not high enough; perhaps they should consider higher tolls during the rush hour, the same way commuter trains do. If cars are Teh Bad because of pollution and AGW, then tolls should be higher everywhere, not just at the bridge (that's essentially what a carbon tax is). Here's the Environmental Defense Fund on the subject. Furthermore, bridge and road tolls have increased nearly everywhere in the past few years, not just on this private bridge. The tolls on the publicly operated San Francisco Bay Bridge were $1 in 1988, but are currently $4. That's a quadrupling in twenty years, quicker than the cited period of 25 years for the Ambassador. And London has famously begun charging congestion tolls to enter the gridlocked inner zones.

I think we can all agree that we rely on the transportation infrastructure and that we would like for it to be properly maintained. That is essentially a public good (not a pure public good, though). Every unavoidable pot-hole creates potential additional maintenance for the car owner. We would also like to see traffic reduced to the point that we don't experience delays and frustration. But fuel taxes are just one of several responses. Tolls that are reinvested in the roads are a better way of both directing the money to the most used infrastructure and directing the traffic to the best infrastructure. For example, if you had to raise tolls on a freeway to keep up the maintenance due to heavy truck usage to the point that shippers began shifting more of their traffic to more efficient railroads, that would be a good thing, no?

Oh, you did remember that railroads in the US are (for the most part) privately operated and maintained, didn't you?


-----------------------------------
[1] Note the parallel to education: we all know that school buildings, teachers, and books cost money, but the phrase "free education" is used without irony. May I also suggest a small, means-tested toll at public schools? You can call it whatever you want -- "tuition" or "user fee" -- so long as you collect it.

[2] Don't tell the people who believe that private infrastructure is impossible. They prefer the impossibility theorem to the malevolence theorem, but will fall back to the latter when it suits them.
